Overview
Brain MRI may be helpful in the diagnosis of subdural hematoma. Findings on MRI diagnostic of subdural hematoma include crescent shape hematoma which has different intensity in different phases.
MRI
Brain MRI may be helpful in the diagnosis of subdural hematoma. Findings on MRI diagnostic of subdural hematoma include:[1]
Acute subdural hematoma:
- Crescent shape hematoma
- T1: Isointense to gray matter
- T2: Hypointense to gray matter
Subacute subdural hematoma:
- Crescent shape hematoma
- Hyperintense in T1 and T2
Chronic subdural hematoma:
- Crescent shape hematoma
- Isointense to CSF in T1 and T2
Acute on chronic subdural hematoma:
- In case of rebleeding, it appears hyperintense to CSF in T1 and hypointense to CSF in T2
